Researchers discover the source of animals’ natural compasses
For years, biologists have pondered how so many members of the animal kingdom — from fruit flies and pigeons to sea turtles and wolves — are able to navigate long distances apparently by sensing the Earth’s magnetic field. Two theories have emerged in recent years: one that the ability derived from iron-binding molecules, the other that it came from a protein called cryptochrome. Now a team from China’s Peking University have discovered that both theories describe complimentary aspects of the same bio-navigational system.
